The role of hypothalamic-pituitaryadrenal axis genes in individual variance of stress sensitivity

Abstract

The present study aimed to assess the main effects of ten polymorphisms of glucocorticoid (NR3C1) and mineralocorticoid receptor (NR3C2) genes together with gene-by-environment interactions on individual differences in personality traits in 1215 mentally healthy individuals aged 17-25 years. Multiple linear regression analysis demonstrated that prenatal solar activity level modulated the association of rs56149945 (N363S) with Persistence (β = 1.21; Р = 0.001) and rs41423247 in NR3C1 gene with emotional resistance to stress (β = -2.72; Р = 0.005).
